An object falls from rest. Its position at time t is given by s(t) = 1/2 gt^2. We consider that it falls for T seconds. (a) Write its velocity v as a function of time t and then write the velocity as a function of the position s. (b) Notice that v(T) denotes the nal velocity of the object. Write the average velocity v over the object during its fall, rst averaging over time t, and then averaging over position...

At t = 0, Ball 1 is dropped from the top of a 19 mm-high building. At the same instant Ball 2 is thrown straight up from the base of the building with an initial velocity of +12 m/sm/s. Assume that Ball 1 starts from rest and that air friction can be ignored. At what height will the two balls pass each other? What is the velocity of each ball at the moment they are at the same height?  Express...

A ball is dropped from rest from the top of a 6.10 m-y’all building, falls straight downward, collides inelasrically with the ground, and bounces back. The call loses 10.0% of its kinetic energy every time it collides with the ground. How many bounces can the ball make and still reach a windowsill that is 2.44 m above the ground?

Typed please. Consider a bouncy ball dropped off of a building (ignoring air resistance). What are the velocity and acceleration of the ball at the instant of release? Is it speeding up or slowing down? What are the velocity and acceleration of the ball after 1s, before hitting the ground? What is the speed of the ball after 1s? Is it speeding up or slowing down?​

A 40-g ball is initially at rest at position A and then drop onto a horizontal floor. Just before impact with the floor( position B), the ball has a speed of 5.5m/s. It remains in contact with the floor for 0.15s before bouncing off. Its speed just after losing contact with the floor is 3.0m/s. Neglect air resistance. For the duration that the ball is in contact with the floor, determine (a) the displacement of the ball from position A...
